This module is taking up too much memory.

## My Problem
- When installing and importing vertexai, it immediately takes up about 250MB.
```
# uv add google-cloud-aiplatform
import vertexai
```

- So, if I'm using eight multiprocessors, adding this module alone will increase my base memory usage by about 2GB.

## Question
- I think this is too heavy for a single module.
- Where does this massive size come from? Is it because of the numerous shared libraries?
- Is there a way to reduce the memory footprint of the module?

Reproduce the reported memory increase using the shown `uv add google-cloud-aiplatform` and `import vertexai` steps, then inspect the package's dependencies and imported shared libraries. Done means identifying the main source of the roughly 250 MB footprint and determining a concrete, validated way to reduce it.
